It would be helpful if you are doing a lot of "anything-crunching,"
whether that be numbers, pointers, integers, or whatever. If your CPU
is very busy, _with multiple tasks_, adding a CPU could indeed be
helpful.
If, on the other hand, your system is largely I/O bound, that is, you
are typically:
- Waiting for screen updates due to slow graphix card;
- Waiting for data to come in from disk;
- Waiting for swap space [e.g. - memory starved system]
Adding a second CPU would really not help you much.
Indeed, it may be difficult to harness it without having extra memory
that might readily cost more than your computer is worth...

Downloaded the 3c90x-1.0.0i.tar.gz file from 3Com. It does not want to
compile with the 2.4.0-test12 kernel. In fact, the kernels listed in
the README are all rather old.
*hour of research later*
Read the current archive http://www.scyld.com/pipemail/vortex/ it
seems that there is an issue with the 3c905cx cards. I don't
particularily follow what they are talking about. Since this is the
card I have installed in the box I will swap it out with a card I know
works and wait for the gurus to get things sorted out.

The permissions for the floppy devices should be: 660. That is, as root:
chmod 660 /dev/fd0*
Then, you need to make all users that are allowed to use the floppy drives
members of the group: floppy
At least that is doing it by the book.
Also check the permissions of the mount point. If it is root:root then it
needs to be 666. Unless you need something else for security reasons.

Subject: Problems getting CDRECORD to burn 99min CDS..bug?
Date: Fri, 15 Dec 2000 03:05:31 -0000
Had anyone tried using CDRECORD to burn 90+ min ?
Well I tried it with the Mitsumi 4804TE drive and when it gets towards the
end
of the DISK... it fails.. this is despite giving it -ignsize flag.
Looking at a typical ATIP for a 90min CD:
ATIP info from disk:
Indicated writing power: 4
Is not unrestricted
Is not erasable
Disk sub type: Medium Type A, low Beta category (A-) (2)
ATIP start of lead in: -14892 (96:43/33)
ATIP start of lead out: 359849 (79:59/74)
They stored the real capacity in the lead in, maybe thats why it does not
work?
Here are the errors:
CDRECORD.EXE: Could not set realtime priority.
Starting to write CD/DVD at speed 2 in dummy mode for single session.
Last chance to quit, starting dummy write in 1 seconds.

There must be a way to burn 90min CDs
with this program... what is this error?
(this is using the windows port cause my linux drive is being fixed)
Anyway anyone smart enougth to make a quick patch to fix this?

Subject: ATAPI device hdd error
Date: Fri, 15 Dec 2000 03:09:34 GMT
Hi
I have been trying the different linux distributions recently and I
noticed that there is always this error message given below during
installation:
ATAPI device hdd:
Error: Not ready -- (sense key=0x02)
(reserved error code) -- (asc=0x3a,ascq=0x01)
The failed "Read Cd/Dvd Capacity" packet command was
"25 00 00 00 00 00 00 00 00 00 00 00"
hdc: cdrom_decode_status: status=0x51 {DriveReady SeekComplete Error}
hdc: cdrom_decode_status: error=0x34
I have a Creative PC-DVD 8x as Master and Matshita 8x/4x CD-R/RW as
Slave on the secondary IDE.
Does anyone know what's wrong here? They work perfectly on my Win98
partition and Linux distros. No problem reading from or writing to
them. Just curious abt the error messages. On RH7, the console screen
would keep repeating these messages and store them in dmesg.
Thanks in advance.

At the risk of being redundant:
Section "Screen"
Identifier "Screen 1"
Device "ATI Rage IIC"
Monitor "NEC MultiSync3V"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1024x768"
ViewPort 0 0
EndSubsection
EndSection
Ad some other Modes if you want, need, and you monitor can support them.
But this isn't enough, you have to have the proper horizontal refresh
and vertical sync rates. And, don't enter something that your monitor
won't handle or you may give new meaning to the term "smoke test".
Section "Monitor"
Identifier "NEC MultiSync3V"
HorizSync 31.5 - 48.5
VertRefresh 50-70
EndSection
The above range will support 1024 x 768.
These are copies from my XFree86Config file.
And, I presume that your driver (device) is also correct:
Section "Device"
Identifier "ATI Rage IIC"
Driver "ati"
#VideoRam 4096
EndSection
The documentation says not to tell it how much VRAM you have unless it
can't figure it out for itself -- put in the figure, but leave it
commented out.

I have a 3com 3c509b (not TPO) - I had to boot to dos and use the disk
supplied with the card to disable plug + play. After that it worked OK.
It appears you are relying on probing to find the card, this might not work.
try this:
modprobe 3c509
ifconfig -a
to see if you can find it.

Same card, same problem your fix looks good;
modprobe 3c509
ifconfig -a
followed by netcfg under Xwindows , forcing the card "active" - and I can
now ping my own machine.

I think the 96:43/33 are not correct. I get the following from a 80 min
CD:
ATIP info from disk:
Indicated writing power: 5
Is not unrestricted
Is not erasable
Disk sub type: 3
ATIP start of lead in: -12514 (97:15/11)
ATIP start of lead out: 359849 (79:59/74)
Disk type: Long strategy type (Cyanine, AZO or similar)
Manuf. index: 22
Manufacturer: Ritek Co.
and this form a 74 min CD:
ATIP info from disk:
Indicated writing power: 5
Is not unrestricted
Is not erasable
Disk sub type: 6
ATIP start of lead in: -11640 (97:26/60)
ATIP start of lead out: 337350 (75:00/00)
Disk type: Long strategy type (Cyanine, AZO or similar)

So you have a 80 min CD.
